Corn, besides, or whatever else is the common and favourite vegetable food of the people, constitutes, in every civilized country, the principal part of the subsistence of the labourer. In consequence of the extension of agriculture, the land of every country produces a much greater quantity of vegetable than of animal food, and the labourer everywhere lives chiefly upon the wholesome food that is cheapest and most abundant. Butcher’s meat, except in the most thriving countries, or where labour is most highly rewarded, makes but an insignificant part of his subsistence; poultry makes a still smaller part of it, and game no part of it. In France, and even in Scotland, where labour is somewhat better rewarded than in France, the labouring poor seldom eat butcher’s meat, except upon holidays, and other extraordinary occasions. The money price of labour, therefore, depends much more upon the average money price of corn, the subsistence of the labourer, than upon that of butcher’s meat, or of any other part of the rude produce of land. The real value of gold and silver, therefore, the real quantity of labour which they can purchase or command, depends much more upon the quantity of corn which they can purchase or command, than upon that of butcher’s meat, or any other part of the rude produce of land.
Such slight observations, however, upon the prices either of corn or of other commodities, would not probably have misled so many intelligent authors, had they not been influenced at the same time by the popular notion, that as the quantity of silver naturally increases in every country with the increase of wealth, so its value diminishes as its quantity increases. This notion, however, seems to be altogether groundless.
